General description
The 74ALVT162827 high-performance BiCMOS device combines low static and dynamic
power dissipation with high speed and high output drive. It is designed for V
CC
operation
at 2.5 V or 3.3 V with I/O compatibility to 5 V.
The 74ALVT162827 20-bit buffers provide high performance bus interface buffering
for wide data/address paths or buses carrying parity. They have NOR Output Enables
(nOE0 and nOE1) for maximum control flexibility.
The 74ALVT162827 is designed with 30 Ω series resistance in both HIGH and LOW
output stages. This design reduces the line noise in applications such as memory
address drivers, clock drivers and bus receivers/transmitters.
